Alot of european states had a increase in their war making capasity. The amount of people that went on the crusades was not even close percentage wise to the drain of manpower in the world wars so there was no shortage of men back home. There is also a huge change in castle and fort building technology that the crusaders bring back from the middle east along with valuable combat experience.
